Is the egg encrusted in diamonds? Does the egg have a popular YouTube channel you’ve never heard of? Is a sexy celebrity holding the egg?

Nope. None of the above. Just an egg.

Here’s the egg.

That’s it. That’s the egg more than 25 million accounts have liked as of Monday morning, when it was still gaining likes at a rapid pace.

We do not yet know who posted the egg on Jan. 4, why it was posted, or why this attempt to set a record actually worked.

Nor do we offer grand perspective on why this happened. Sometimes, the will of the internet just bends in peculiar ways, and in this case, the internet decided it was into that egg.

Still, you would scoff at the cultural significance of the egg at your own peril. For perspective: Last year’s top television show in the United States, “Roseanne,” averaged 20 million viewers per week. If everyone who liked the photo created a new city, it would be the world’s second-largest, beating Shanghai. The egg’s fans have passed the population of Australia.

At that scale, internet frivolity starts to look a little less frivolous.

It’s not the first time that internet users, showing a thirst for chaos, have displaced meaningful record holders in favor of a lighthearted gag. In 2017, the internet coalesced behind Carter Wilkerson, a 16-year-old high school student who set a Twitter record for retweets after asking Wendy’s for free chicken nuggets. (He was recently dethroned by a Japanese businessman, under the handle @yousuck2020, who got more than five million retweets when he offered about $9,250 to 100 random people who retweeted him.)

The comments on Ms. Jenner’s birth announcement, now Instagram’s second-most liked post with about 18.3 million likes, were covered in egg. The egg’s supporters taunted her, often using the egg emoji or simply the word “Egg.”

In response, Ms. Jenner posted a video of herself cracking a similar-looking egg on the pavement.

“Take that little egg,” she wrote.

The world-record egg-posting account, hinting at a mysterious Phase 2 of the egg plan, wrote on Instagram that “it doesn’t end here,” and that “we’re only just getting started.”
